A new factor causing the superposability of collisionally activated decomposition spectra of ions to fail has been established for isobaric ions. If the two isobaric ion beams are not transmitted in their entirety simultaneously to the collision cell, the resulting spectrum is not a linear combination of the two spectra of the individually transmitted complete ion beams. Apparently the energy content of collimated ions varies across the ion beam, so that transmission of different portions of the ion beam produces samples of ions with different energy contents.
